JOHN T. H. MITCHELL, F HICAGO, ILLINOIS.

ADVERTISING DEVICE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed March 18, 1907- Serial No. 362,932.

To all whom it may concern:

Be it known that I, JOHN T. H. MITCHELL, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Advertising Devices,

' of which the following is a full, clear, and exact description, such as will enable others skilled in'the art to which it appertains to make and use the same.

My invention relates to advertising devices, and has particular reference to improvements in such as partake of the character of postal letters or cards.

The object of my invention is to provide a combined circular letter and envelop, in which a return postal or other article or sample may be inclosed and sent through the mails.

My invention consists generally in a substantially rectangular, ungummed sheet of thick paper or cardboard having a letter or other communication printed upon its inner face, said sheet being transversely scored upon two lines to form an intermediate portion and two end portions or flaps, and one of said portions being provided with tongues or lugs struck up from the body thereof, to hold an inserted piece, card, or sample, suitable means being provided for fastening the sheet in folded condition.

My invention will be more readily understood by reference to the accompanying drawings, forming part of this specification, and in which Figure 1, is a perspective view of the inner side of an advertising device embodying my invention. Fig. 2, is a perspective view of the device folded and sealed, ready for mailing.

As shown in the drawings, in carrying out my invention I prefer to employ a substantially rectangular sheet of thick paper or card-board. The inner face of this sheet bears a commercial letter, or other communication, which is printed thereon. The sheet is scored upon two transverse lines, 22, which divide the sheet into an intermediate portion, B, and two end flaps or portions, A and B. The portion A is of substantially the same width as the portion B, while the portion 0 is usually narrower, the same being intended to fold between the other portions as indicated. As means to hold a postal card or other insert, such as a sample or other article to be sent to the addressee. I provide the tongues or lugs, 3, which are struck from the body of the sheet. In the preferred form these tongues are formed in the bottom or lower flap; C, of the sheet. The tongues point inwardly and thus present their solid portions to the edges of a post card or the like, 3, as shown by dotted lines in Fig. 1. Obviously, the lugs prevent endwise movement of the insert, whatever its kind, upon the sheet. When the insert has been thus secured, the flaps are folded upon the intermediate portion, the lower flap being folded beneath the upper flap. Then the upper and intermediate flaps are fastened together by a small sticker, or seal. 4, as shown. Thus secured between the folds of the sheet, and held by the end engaging lugs or tongues. 3. the inserted piece cannot possibly escape, imtwithstanding the fact that the folded device forms an open-ended envelop. The advantage in this regard is that the device may be sent through the mails as third class matter. I have referred to the device shown as the preferred form of my invention. In explanation thereof, it may be stated that the reason for its preference is that the tongues, being contained in the portion which is folded within the other portions, are concealed and protected and the folded sheet presents smooth sides,

- not likely to be torn in the mails.

Having thus described my invention. I claim as new. and desire to secure by Letters Patent,

An advertising device comprising a substantially rectangular sheet of thick, ungummcd paper, or cardboard. to bear a letter or communication upon its inner face. and transversely scored. the lower portion or flap of said sheet being provided with struck up lugs or tongues. extending inwardly to secure an insert against endwise movement when the sheet is folded, and a fastening upon the free edges of the folded sheet. substantially as described.

In testimony whereof, I have hereunto set my hand, this 11th day of March, 1907, in the presence of two subscribing witnesses.

- JOHN 1. II. MITCHELL.
